QUARRY-FRAME FOR ROCK-DRILLS.

SPECIFICATION forming part of Letters Patent No. 365,733, dated .Tune 28, 1887.

Application led Jul)- 26,1886.v Serial No 209,l05. (No model.)

To all whom, it may concern:

Be it known that I, GEORGE R. OULLING- WORTH, ofthe city and county of New York, in the State of New York, have invented a new and useful Improvement in' QuarryFrames for Bock-Drills, ot' which the following is a speciiication.

My invention relates to a frame employed for supporting a rock-drill for quarry-wonk, so that the drill may be shifted horizontally, in order to drill a line or row of holes at any desired distance apart, such a frame comprising an approximately horizontal bar supported at the ends by benches and legs, and a carriage which, by means of a rack and pinion, may be moved along the bar in a direction lengtl1- wise thereof, and to which the rock-drill is secured.

My invention is more particularly intended for machines in which the bar hasta T-shaped transverse section, the rack being secured to the horizontally-entending web of the bar; and an important object of my invention is to provide a carriage which may be cheaply-con-v structed and fitted to the bar at a slight eX- pense, and to which the rockdrill may be secured adjustably, so as to provide for swing ing the drill at different angles in the plane of movement of the carriage, or, in other words,

at different angles in a plane parallel with the face of the bar.

The invention consists in novel features of construction and (om'oinations of parts,which are hereinafter described, and pointed out in the claims. Y

In the accompanying drawings, Figure l is a plan of a quarry-frame embodying my in` vention. Fig. 2 is a transverse vertical sec tion thereof upon the plane of the dotted line x so, Fig. l, and showing also a portion of the drill-back which is secured to the carriage. Fig. 3 is a similar transverse section on the plane indicated by the dotted line g/ y, Fig. l, looking toward the right hand from said line. Fig. 4 is a rear elevation of a portion of the horizontal bar and the carriage which is titted thereto; and Fig. 5 is a transverse section upon the plane of t-he dotted line c z, Fig. l, also looking toward the right hand from said dotted line.

Similar letters of reference designate correspending parts in all the iigures.

A designates the approximately horizontal bar, which is supported at opposite ends by benches or cross-bearers B, provided with legs B. As best shown in Figs. 2, 3, and 5, the bar A is ot' Tfshaped transverse section, with a rack, b, secured upon its horizontally-extending web t. The bars A, when of such transverse section, may be readily made from rolled I-beams by simply cutting the beam in two parts lengthwise oll the web and midway between its ilanged sides, one beam therefore being made to produce the bars for two drillframes. Y

In order to provide for turning the bar A so that the rocledrill, which is secured to the carriage O, as I shall soon describe, may be swung in a plane transverse to the length ot' the bar, I have represented the benches or bearers B as provided with circular bearings b, to which are fitted circul'ar heads or divided journals B2, as best shown in Fig. 5. These divided heads or journals B2 have in their meeting faces apertures which l'itapproximately the transverse section of the bar A, and

such heads or journals may be clamped securely in place by tightening-bolts c, applied to the caps b of the bearings, wherein they are iitted. Vhen the bolts c are loosened, the bar A and its heads orjournals B2 may be turned readily in the bearings b2, 'so as to present the drill supported by the carriage C at different angles in a plane transverse to the length of the bar A. After being thus adjusted to proper position, the heads or journals-B2 and the bar A may be secured in position by tightening the bolts c, and thereby clamping the heads or journals B2 against turning in the bearings b2.

As here represented, each Vleg B is secured in place by a post, This post B3 has at one end a head or flange, c', and it is inserted through a circular hole or bearings, c2, in the end portion of the bench or bearer B. The leg B is inserted transversely through the post B3 on the side of the bearer opposite the head or flange c', and in the outer end of the post is aset-screw, c, which bears against the leg B. lVhen the set-screw c3 is loosened, the post B3 may be turned easily in its seat or socket, so as to swing the leg in a plane transverse to the length of the bar A, and the leg B may also be slipped more or lessthrough '4 5 against slipping endwise through the post B3.

The carriage C consists, as here represented, of upper and lower members, G G2, which have a bearing upon the top and bottom flanges, t, of the bar A, and which also have a bearing upon the rear edge of the web b of 1 said bar, as shown in Figs. 2 and 3. The upper and lower parts, C CZ, of the carriage have rearwardly-extending arms c4, which are secured firmly together in rear of the bar A by bolts c5 at the front of the bar. The upper and lower members, C' C2, are secured together by tie-pieces C3, which extend transversely across the face of the bar A, and l bear against said faces and front faces of the members C' G2, being approximately. coincident with the face of the bar A. The upper and lower members, C' C2, of the carriage are provided with segmental lips or flanges c", forming between them a circular seat, the faces of which receive a projection, D, upon the drill-back. In the upper and lower members, C C, of the carriage are also provided segmental slots c7, which are formed with less radius than the segmental lips or iianges c, but from the same center, and said slots receive bolts es, which are fast in the projection D of the drill-back, as shown best in Fig. 2, and which have nuts applied to their outer ends, whereby they may be clamped in any position in the segmental slots c7. rlhe slots eT provide for swinging the drill-back D in a plane parallel with the face of the bar A, so that the drill or bit will be presented at different angles in said plane, and after the drill-back has been thus adjusted relatively to the carriage it may be secured in place by tightening the nuts upon the bolts es.

The carriage Gis provided with apinion, d, which engages the rack I), and by which the carriage may be moved along the barA. The inner end of the pinion-shaft ts abearing, d', consisting of a socket formed in the upper member, C', and on the opposite side of the Vpinion the pinion-shaft has a bearing in a bridge-piece, di, extending horizontally across the back of the upper member, C', of the carria'ge.

It will be understood that the carriage above described is of very simple construction, and that it only'need have a bearing upon the top and bottom flanges of the bar A and upon the rear edge of the horizontally-extending web b.

What Iclaim as my invention, and desire to secure by Letters Patent, is-

1. In a quarry-drill frame, the combination, with a bar provided with a rack, of a carriage fitted to slide thereon and provided with a pinion for engaging the rack, and having upon its face a circular seat for the reception of a projection on the drill-back, and segmental slots for receiving bolts to secure the drill to the carriage, substantial] y as herein described.

2. In a quarry-drill frame, the combination, with a bar of T-shaped transverse section, havinga rack secured to its horizontally-extend ing web, of a carriage composedof upper and lower'members connected together behind the bar and bearing upon the top and bottom flanges and on the rear edge of the web of the bar, and a pinion journaled in the carriage for engaging the said rack, the carriage being constructed for the attachmentof a rock drill, substantially as herein described.

3.' The combination, with the bar A of T- shaped transverse section, provided with the rack b, of the carriage comprising the upper and lower men1bers,C C2, fitted to slide on the top and bottom anges of the bar and bolted together behind the bar, and provided with segmental lips c, for receiving a projection on the drill-back, and with the segmental slots c?,

the tie ieces C3 connectino said u er and P s PP lower members and bearingon the face of the bar A, and a pinion, d, journaled in the carrivage, substantially as herein described.
